Understanding Age Expressions

The video tutorial guides students through solving an age-related problem involving three individuals: Jose, Felipe, and Maria. It begins by introducing the problem and setting up expressions for each person's age based on given relationships. The tutorial then demonstrates how to use the distributive property to simplify the expression for Maria's age, ultimately arriving at a simplified expression. The lesson emphasizes understanding relationships and applying algebraic properties to solve real-life problems.

What is the age difference between Jose and Felipe?

• Felipe is 2 years older than Jose.

• Felipe is 5 years older than Jose.

• Felipe is 3 years older than Jose.

• Felipe is the same age as Jose.

If Jose is X years old, how can we express Felipe's age?

• X + 2

• X - 2

• X + 3

• X * 2

How is Maria's age related to Felipe's age?

• Maria is the same age as Felipe.

• Maria is half the age of Felipe.

• Maria is three times as old as Felipe.

• Maria is twice as old as Felipe.

What mathematical property is used to simplify Maria's age expression?

• Identity Property

• Associative Property

• Commutative Property

• Distributive Property

What is the first term in the expression for Maria's age?

• 3X

• X + 2

• X

• 2X

What is the simplified expression for Maria's age?

• X + 6

• 3X + 2

• 3X + 6

• X + 2

How do you calculate the second term in Maria's age expression?

• Add 3 to X

• Subtract 2 from 3

• Multiply 3 by 2

• Multiply 3 by X
